Geothermal Incentive Checker by State (2026)
Select a state to create a safe verification checklist. Confirm every amount with the administering agency or utility before purchase or installation.
What this checker can and cannot do
It can give you the correct verification sequence. It cannot know your utility territory, income qualification, equipment model, contractor status, funding reservation, tax situation, or whether a program changes after this page is published.
Federal baseline: the 30% Section 25D residential credit is unavailable for new property installed after December 31, 2025.
Frequently asked questions
Why does this tool not show a guaranteed state amount?
Because state, utility, income, equipment, and timing rules differ. A hard-coded number can become wrong before a homeowner signs a contract.
Does choosing a state prove eligibility?
No. Use the checklist to obtain written confirmation from the actual program administrator.
